            Storage and Cleanup
          
        
        
          Shelf life is 6 months, in original, unopened
        
        
          factory containers, under normal storage
        
        
          conditions of 55° to 85° F. Do not store in direct
        
        
          sunlight. Keep drums tightly closed when not in
        
        
          use. Cured product may be disposed of without
        
        
          restriction. Excess liquid ‘A’ and ‘R’ material
        
        
          should be mixed together and allowed to cure,
        
        
          then disposed of in the normal manner.
        
        
          
            Safe Handling of Liquid Components
          
        
        
          Use caution in removing caps and bungs from the
        
        
          container. Loosen caps and bungs first to let any
        
        
          built up gas escape before completely removing.
        
        
          Avoid prolonged breathing of vapors. In case of
        
        
          chemical contact with eyes, flush with water for
        
        
          at least 15 minutes and get medical attention.

            Caution
          
        
        
          Polyurethane products manufactured or
        
        
          produced from this liquid system may present a
        
        
          serious fire hazard if improperly used or allowed
        
        
          to remain exposed or unprotected. The character
        
        
          and magnitude of any such hazard will depend
        
        
          on a broad range of factors which are controlled
        
        
          and influenced by the manufacturing and
        
        
          production process, by the mode of application
        
        
          or installation and by the function and usage
        
        
          of the particular product.
